GEORGE GARDNER, OF NEWV YORK, N. Y.

IMPROVEMENT IN UNDERSHOES OR SLIPPERS.

Specification forming part of Letters Patent No. 212,370, dated February18, 1879; application filed January 15, 1879.

To all whom it may concern:

Be it known that I, GEORGE GARDNER, Of New York, in the county of NewYork and State of New York, have invented certain new and usefullmprovements in Undershoes or Slippers; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification, and in which- Figure 1 is a perspective view of myimprovement in foot-wear, partly broken. away. Fig. 2 is a sectionalview thereof, and Fig. 3 is a perspective view of a modification.

The same part in the several figures is denoted by the same letter.

My invention appertains to certain improvements in foot-wear adapted tobe worn under the boot or shoe; and it consists of an envelope oftextile or other suitable material having an intermediate septum orlining of paper, or its equivalent; secondly, of the upper and sole, oneor both, of a double thickness of textile material, forming anintermediate air-space provided with a septum of paper or other suitablematerial, the upper and sole being of the same or dissimilar material,adapted to be worn under the boot or shoe; and, thirdly, of an envelopeof textile material having an intermediate space provided with a septumor lining of paper, substantially as hereinafter more fully describedand claimed.

In the accompanying drawings, A refers to an undershoe made entirely ofa light textile material-paper-muslin or similar material. It is made oftwo pieces, the upper to sewed together at the heel and to the bottom orsole a. This construction lessens the number of parts, and consequentlysaves time and labor in the making of the shoe or article.

Another form ofmaking my shoe is to double the thickness of thematerial, so as to provide a space, 1), within which is interposed'orplaced an intermediate filling or lining of paper, B

- 7 as exhibited in Fig. 3.

This form of shoe pro duces a warm, comfortable, and inexpensivecovering for the foot.

In lieu of the lining or filling of paper, any other material which is anon-conductor of heat may be used.

Among some of the advantages incidental to my invention is, that itserves as a substitute for overshoes, which is not only desirable forwalking, but also for riding in winter. It can, however, be used inconnection with overshoes in very cold weather, if desired. Its cost isso trifling that it can be made for less than the cost of washingvanarticle of wearing apparel, which avoids any trouble arising from thatsource.

In the manufacture of my article of foot wear, I do not wish to confinemyself to any particular kind of textile material or non conductor;neither do I restrict myself to any particular method in making thesame, but reserve the right to use any kind of non ducting material orthin textile material I may desire, and any'process by which the desiredresult may be attained in the best and cheapest manner.

In lieu of the paper as a lining, any other light material that willconform to the foot and act as a good non-conductor can be em ploycd.For this purpose oil-silk might be used.

I do not confine myself to the particular arrangement of the material,as, instead of plae ing the paper inside and the textile materialoutside, this arrangement may be reversed,

Having thus fully described my invention,

I claim and desire to secure by Letters Pat ent- 1. A slipper adapted tobe worn under the boot or shoe, composed of an envelope of tex adaptedto be wornunder the boot or shoe, substantially as and. for the purposespecified.

3. As an improved article of manufacture, an article of foot-Wearadapted to be Worn under the boot or shoe, consisting of an envelope oftextile material having an intermediate space provided with a septum orlining of paper, substantially as shown and described.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two Witnesses.
